Using the prctl Command

Use the prctl command to make runtime interrogations of and modifications to the
resource controls associated with an active process, task, or project on the system.
See the prctl(1) man page for more information.

How to Use the prctl Command to Display Default Resource Control Values

This procedure must be used on a system on which no resource
controls have been set or changed. There can be only non-default entries in
the /etc/system file or in the project database.

Use the prctl command on any process, such as the current shell that
is running.
